Positioned et substantially opposite sides of the valve cesing i ere lugs 19 and 20 which indicate the extreme limit of tra-Vel of the Valve 'member 7 end finger or erm 16. it will be perfectly evident that when finger 10 is against one of the Stops that the vulve is entirely closed end can not be further moved in 'e closed position Without breaking finger 10, end-when against the other stop it is in its extreme open posi tion end can not be further opened or roteted in that direction.

In operation the valve is secured'riii position and when any desired quantity of steam or water or other liquid controlled by ,the Vel-veis desired,`veive ineniber Ais rotated by' wheel 15 end the indicator or 'finger i() moves to e corresponding position to 'relire member 'Y sind indio ttes the ernennt of liquid permitted to pass through the valve.
